The establishment of JSP running and developing environment under Linux

JS First, install JDK 1.4.2
　　


Although the recent version of Jsk and JRE is 1.5.0, the company's developers are unified by 1.4.2.


　　


the process of installing JRE and JDK is nothing to say, install with RPM package, fool will. Configure the environment variables after loading:


　　


Vi/etc/profile


　　


at the end of the configuration file, add a few lines:


　　


java_home=/usr/local/java/jdk1.4.2_08


classpath=.:/ Usr/local/java/jdk1.4.2_08/lib/dt.jar:/usr/local/java/jdk1.4.2_08/lib/tools.jar


Path=/usr/local/java/jdk1.4.2_08/bin: $PATH


export PATH java_home CLASSPATH


　　


then save and exit, execute:


　　


Source/etc/profile


　　


in this way, the environment variables that have just been written are in effect.


　　


Test:


　　


[imga][root@scientific bin]# java-version


java Version "1.4.2_08"


Java (TM) 2 Runtime environment, Standard Edition (build 1.4.2_08-b03)


Java HotSpot (TM) Client VM (build 1.4.2_08-b03, mixed mode)


[root@scientific Bin]#[/imga]


　　


and then write a small program to test:


　　


[root@scientific bin]# cd/home/xinsoft/mydev/java/


[root@scientific java]# VI Test.java


　　 　


Save, check out:


　　 　


can be seen that we have configured the jre1.4.2+jdk1.4.2.


　　


Two, install Tomcat


　　


below we'll install Tomcat.


　　


first download the Tomcat version we need from http://www.apache.org/and install it.


　　


[Root@scientific v5.0.29]# CP jakarta-tomcat-5.0.29.tar.gz.tar/usr/local/


[root@scientific v5.0.29]# cd/usr/local/


[root@scientific local]# chmod +x Jakarta-tomcat-5.0.29.tar.gz.tar


[root@scientific local]# tar zxpf jakarta-tomcat-5.0.29.tar.gz.tar


　　


Next Configure the environment variable:


　　


Vi/etc/profile


　　


in configuration file last add:


　　


catalina_home=/usr/local/jakarta-tomcat-5.0.29


　　


Export Catalina_home


　　


disk exit, then: Source/etc/profile


　　


the configured environment variable to take effect immediately.


　　


Start Tomcat:


　　 　


then visit Tomcat:


　


can be seen Tomcat we also installed.


　　


Three, combine Apache with Tomcat
with Tomcat-connector

　　


my Apache is scientific Linux 4.0, the version is 2.0.54





first download the appropriate tomcat-connector from http://archive.apache.org/dist/jakarta/tomcat-connectors/jk2/to local.


　　


copy mod_jk2.so to the Apache modules directory:


　　


[root@scientific i386]# CP mod_jk2-2.0.43.so/usr/lib/httpd/modules/


　　


Edit Apache httpd.conf file:


　　


vi/etc/httpd/conf/httpd.conf


　　 　


Edit Tomcat's Server.xml file


　　


Vi/usr/local/jakarta-tomcat-5.0.29/conf/server.xml


　　


as shown in the following figure: Add this line: <context path= "docbase=" "debug=" 0 "/>


　　 　


this place tomcat4.x slightly different from the Tomcat 5.x. The Tomcat5.x,<context path= "docbase=" debug= "0"/> can be commented out.


　　


edit Tomcat's jk2.properties


　　


vi/usr/local/jakarta-tomcat-5.0.29/conf/jk2.properties


　　


can temporarily not change it, so that its parameters are the system defaults;


　　


Edit Apache Workers2.properties


　　


vi/etc/httpd/conf/workers2.properties


　　


Note The final URI mapping, which allows you to add multiple mappings, but the added mappings must be accessible. For example, in the above figure we have added/xinsoft/* mapping, we must ensure that the/usr/local/jakarta-tomcat-5.0.29/webapps/xinsoft/directory exists.
